Subject: Notes on Numerical Computing
Over the last few years I have developed a set of notes called
"Notes on Numerical Computing", for use in place of a text in an
undergraduate numerical computing class intended for computer science
students (rather than math or engineering students).
The philosophy of these notes is to teach a small number of key ideas
in detail, instead of a lot of material. Topics which are emphasised are
the IEEE floating point standard and systems of linear equations, with
additional material on nonlinear equations, integration and ODE's.
The floating point standard material in particular contains much information
that is hard to find elsewhere. Everything is discussed at a low level,
without assuming much prior knowledge. The course is based on PC's,
using mostly Matlab but also some C and a special simulator which
demos many features of the IEEE standard. There is also some
optional material using the MacMath package (which runs only on Macs).
These notes have been used extensively at NYU, and also at McGill, where
Chris Paige made many excellent improvements which have been incorporated.
Years ago many CS depts had a required numerical computing class.
NYU and McGill still do, but most other depts have long since dropped the
requirement. Why? Somehow CS depts (students and faculty) got the idea
than numerical analysis is too hard, or boring, or at any rate not
mainstream computer science. These notes attempt to go the other way:
the material is easily accessible to the average CS undergraduate; and is,
we argue at least, both interesting and important. Student feedback has
been quite favorable.
The notes are reasonably polished but not at a publishable stage. If you
would like to try them in a course you are teaching, and are willing to
give detailed feedback from your experience with them, please send info on
the course title, dates and enrollment.

Subject: Promised "New Estimates for Ritz Vectors" by FTP
At a linear algebra conference last summer I promised several persons
to send a text of my talk. Unfortunately, I have lost their addresses then.
The text, "New estimates for Ritz vectors," has been recently published
as a Tech. Report #677 of Dept. Comp. Sci. at NYU's CIMS, and is available
at our anonymous ftp cite tiger.cudenver.edu, or using URL:
as knyazev_94_Tech_Rep_677_CIMS_NYU.ps.gz (41K).
The purpose is to make clear a behavior of Ritz vectors ...,e.g.\
for a case when the trial subspace is close to an invariant subspace...
Theorem 3.1 shows that the approximation error of an eigenvector
by the corresponding Ritz vector is essentially orthogonal to this
invariant subspace. Theorem 3.2 leads to a dual statement that
the orthoprojection of any eigenvector from the invariant subspace
onto the trial subspace essentially coincides with a Ritz vector.
There is also my eigenproblem-oriented bibliography file
eigenproblem.bib.gz (15K) in the same directory.
Thanks for your attention, Andrew Knyazev

Subject: Release 2.0 of CUTE
Release 2.0 of CUTE is now available
CUTE (Constrained and Unconstrained Testing Environment) is a set of Fortran
subroutines, system tools and test problems in the area of nonlinear
optimization and nonlinear equations. Its purpose is to
- provide a way to explore an extensive collection of problems (over 700
different test problems today),
- provide means of comparing existing packages,
- provide a way to use a large test problem collection with new packages,
- provide a mechanism to manage and update the system efficiently, and
- do all the above on a variety of popular platforms.
The version 2.0 is that corresponding to the paper describing CUTE to appear
in Transactions of the AMS on Mathematical Software.
NEW * The new release provides interfaces to new optimization packages.
* In addition to the existing interfaces for MINOS, NPSOL, OSL, TENMIN,
* UNCMIN, VA15, VF13, VE09 and VE14, CUTE now contains interfaces for
* - COBYLA (MJD Powell derivative free constrained code)
* - MATLAB
NEW * The new release also supports two new computer platforms. Besides
* CRAY/Unicos, HP-UX, DEC/OSF, DEC/ULTRIX, DEC/VMS, IBM/AIX and SUN/SunOS,
* CUTE is now available with fully automated installation procedures for
* MSDOS (with the WATCOM Fortran compiler).
NEW * - The Fortran tools now provide "finite-elements" matrix format for the
* second derivatives.
* - Some driver routines have been improved.
* - Known bugs in the tools and test problems have also been corrected.
CUTE has been written by I. Bongartz, A.R. Conn (both at IBM, Watson Research
Center), Nick Gould (RAL, UK) and Ph. Toint (FUNDP, Belgium). A LaTeX
manuscript detailing the package may be obtained by email from any of the
authors. It is also included in the distribution.
CUTE 2.0 is written is standard ANSI Fortran 77. Single and double precision
versions are available. Machine dependencies are carefully isolated and
The package may be obtained in one of two ways. Firstly, the reader can
obtain CUTE electronically (and free of charge) via an anonymous ftp call to
the account at the Rutherford Appleton Laboratory joyous-gard
(Internet i.d. 18.104.22.168, in the directory pub/cute), or at Facultes
Universitaires Notre-Dame de la Paix (Namur) thales.math.fundp.ac.be (Internet
i.d. 22.214.171.124, in the directory cute). We request that the userid is given
as the password. This will serve to identify those who have obtained a copy
In addition, there is a CUTE www page on
Secondly, the package can be obtained on a floppy disk or magnetic tape at a
minimal price, intended to recoup the costs of media, packaging, preparation
and courier delivery. Potentially interested parties should contact Ph. Toint
to obtain a suitable order form.

Subject: Report Distribution from University of Toronto
We plan to change the way we distribute reports. In the past, we
mailed reports to all those on our technical reports mailing list as
reports were issued. As our mailing list has grown and postage and
photocopying charges have increased, this has become quite expensive.
Moreover, we believe that many people who receive these reports may not
actually want them.
Advances in technology now allow us to adopt a better report
distribution scheme. If we produce an official departmental technical
report, we will mail it to the libraries on our reports list, but we
normally will not mail unsolicitated reports to individuals. Moreover,
many papers will not be made into official departmental technical
reports, but will be available in electronic form in our reports
Our new plan is to periodically e-mail a list of the titles of recent
reports to interested people with instructions on how to obtain any
report they wish to obtain by anonymous ftp. If you recently received
such a note from me, then your name is already on our reports mailing
list, so you need not reply to this message unless you want your name
removed from our mailing list. If you didn't receive such a note from
me, but you wish to have your name included on our mailing list, please
send me (firstname.lastname@example.org) an e-mail message requesting that I add
your name to our list. Please include your complete snail-mail address
as well in case we ever need it.

Subject: LIPSOL beta-2.1 Release
January 24, 1995
LIPSOL (Linear programming Interior-Point SOLvers) is a package that
uses Matlab's sparse-matrix data structure and MEX utilities to
achieve both programming simplicity and computational efficiency.
--- What's New? ---
(1) All sources for MEX-files included
Release Beta-2.1 includes all the sources for the LIPSOL
MEX-files: namely, the newly released version 0.2 of the ORNL
sparse Cholesky package by Dr. Esmond Ng and Dr. Barry Peyton
(along with Dr. Joseph Liu's multiple minimum degree ordering
routines), and our MEX interface routines.
(2) Performance improved
Though not a major update, beta-2.1 is generally faster than
beta-2. For example, under the default setting it solves PILOT87
in 38 iterations and 485 cpu-seconds on an R4400/150MHz CPU
(-mips2 flag used in fmex). But don't try fit2p unless you have
a LOT of memory and patience.
(3) "Memory leak problem" fixed
The false alarms were caused by the Matlab function SPARSE.
--- What platforms are supported? ---
Release beta-2.1 still contains one binary file for the MPS reader.
It supports: DEC (Ultrix 4.x), SGI (IRIX 5.2), Sun Sparcs (SunOS
4.1.3) and HP (HP-UX 9.0x) workstations. Of course there is no
guarantee that the binary would run on every machine from the above
-- Where to get LIPSOL? --
LIPSOL Beta-2.1 distribution consists of only one file for all
platforms. It can be retrieved through anonymous FTP from:
(also available from the WWW URL: http://math.umbc.edu/~yzhang).
See the README files for information on installing and running

Subject: Parallel Programming on the IBM SP2
The Cornell Theory Center will be offering the following
workshop for academic researchers:
PARALLEL PROGRAMMING ON THE IBM SP2
March 28 - 31, 1995
Registration materials must be received by February 23, 1995.
This workshop will enable academic researchers to exploit the parallel
capabilities of the IBM Scalable POWERparallel System SP2.
The Cornell Theory Center's SP2 consists of 512 RISC processors connected
by a high performance switch. The size and power of this system allow
parallel programmers to decrease the wallclock time needed to run their
programs, or to attack larger problems by running over larger numbers of
nodes. The programming model is distributed memory.
The first three days of this lecture-lab workshop will cover concepts of
parallel programming, PVM (Parallel Virtual Machine) from Oak Ridge
National Laboratory, the IBM MPL message passing library, and additional
tools for development and analysis of parallel programs.
- SP2 Message Passing Library -- MPL
- Parallel Virtual Machine (PVM)
- Message Passing Interface (MPI) Overview - Performance Optimization
- Scaling to Exploit Parallelism
- Parallel Tools for Development/Debugging
The final day of the workshop will consist of special topics seminars.
Each of the special topics sessions will be limited to 10 people.

Efficient manipulation of (some) real numbers in computers is a new
frontier! Many interesting theoretical and algorithmic problems are
linked with that topic, and belong to quite distant fields such as
computer science, number theory, numerical analysis, computer algebra
and logics. The aim of this special issue of TCS is to present the
state of art in this increasing new domain, gathering contributions
coming from these different aeras. Researchers working on questions
related to real computer arithmetic are encouraged to present the
theoretical or algorithmic aspects of their results.

Subject: Position Available at MIT
The Research Laboratory of Electronics and the Computational
Hydrodynamics Facility at MIT has a postdoctoral position available in
developing adaptive numerical software for solving 3-D potential
problems. In particular, the research will focus on finding robust
approaches for adaptive gridding which efficiently fit with fast
integral formulation solvers based on the recently developed
fast-multipole and transform sparsification techniques. A variety of
application problems from electromagnetics, electromechanics, and
hydrodynamics will be used to determine approach and software
effectiveness. Candidates must have a PhD in mathematics, computer
science or in computationally oriented physical sciences or
engineering. A strong numerical analysis background and good
programming skills are required, and familiarity with potential theory,
adaptive gridding, boundary-element techniques, or fast-multipole algorithms
will be very helpful. Interested applicants should send a resume by
electronic mail to Professor Jacob White (firstname.lastname@example.org).

problems of mesh generation, adaptive refinement, mesh partitioning,
and the solution of the associated sparse linear systems. A possible
area of additional research is the investigation of virtual environment
visualization techniques for three-dimensional computational models
based on the unstructured mesh work. Part of the effort will include
work on specific finite-element combustion models. Information on the
parallel unstructured mesh computation project can be found at
We seek candidates with expertise in one or more of the following
areas: unstructured mesh algorithm and software design; finite-element
computation; and tool development for scientific computing applications,
particularly in parallel computing environments. Project members have
access to a state-of-the art computing and visualization environment,
including an IBM SP and a CAVE virtual environment system. Nominal
requirements include a Ph.D. in applied mathematics, computer science,
or engineering. Applicants must have received their Ph.D. not more than
three years prior to the beginning of the appointment.
